Body-in-suitcase murder suspect Heather Mack has been sexually assaulted multiple times in her Indonesian prison cell, her lawyer claimed on Monday.

The 19-year-old is not sure whether it was fellow inmates or guards who molested her, her Chicago attorney Michael Elkin told MailOnline. ‘It is very disconcerting,’ he said.

‘She initially thought it was fellow inmates, but now she has discovered that not all the guards are wearing official uniforms.’

Heather was arrested last week along with her boyfriend Tommy Schaefer, 21, over the murder of Heather’s mother, wealthy widow Sheila von Wiese-Mack in the luxury St. Regis hotel on the tropical paradise island of Bali where they were three days into a 10-day vacation.

Mrs Mack’s body was discovered crammed into a suitcase that police claim Heather and Tommy had taken down to a taxi. They left telling the driver they would be back but instead fled to another hotel six miles away near the island’s international airport, according to police.

It is believed that the 62-year-old was bludgeoned to death with a heavy glass ashtray and vase – with such violence that both objects shattered.

Elkin said Heather was distraught when he spoke to her by phone several times overnight. ‘She was tearful, she is being mistreated,’ he said.

He said the information Heather can give him is limited as he is worried their phone calls are being monitored by authorities in Bali. ‘I have told her she can only give me yes or no answers,’ he said.

‘I asked her if she was being mistreated and she said yes. I started going through questions and asked her if she had been touched inappropriately and she said yes. I asked her if it was in the female area and she said yes. I asked her if it was on more than one occasion and she said yes.

‘I asked her if it was consensual and she said no. I could not go into the specifics of whether there was an actual rape or whether it was sexual assault, molesting, call it what you will. I cannot say for sure it was intercourse.’

Heather’s assault claims came after she and boyfriend Schaefer had both complained that they had been given a meal from KFC. Both were outraged that authorities had presumed they would want fried chicken because they are black, claimed news.com.au

‘She told me today she had been given McDonald’s,’ said Elkin. ‘She said she has also been given rice and water, but I am also concerned that she has not had sufficient water.’

Police say they are surprised by the allegations, saying KFC is considered expensive to most Indonesians. Djoko Hari Utomo, chief of police in the island’s capital, Denpasar, said: ‘Heather complains about the food and that she is not being well-treated in jail, nevertheless police treat the prisoners all the same.

He added: ‘Countering the couple’s bizarre claim, he added: ‘We have already given treatment that is more than normal. We give special attention to her as she is still young. This is a transition period for her.’

Elkin confirmed to MailOnline that Heather is expecting a child, but did not know further details. She has been reported as two months pregnant and that it is an ectopic pregnancy and Schaefer is presumed to be the father.
